Incredible
I don’t know what i would do without this! I use it everyday at work to store my milk after I pump! It’s incredible and the lady who designed this is truly a rockstar!! I recommend this to everyone

Convenient cooler bottle
The OG+ is really convenient in ensuring my milk is chilled and remains chilled till i get home. One thing i was surprised about was the warping of the inner freezer chamber after i froze it before using it for the first time. Even though there is a dent below, i guess it’ll still work to keep my milk chilled. Edit: The team at Ceres Chill reached out and offered to send a replacement inner chamber. I really appreciate the service recovery and applaud the team at Ceres Chill for their excellent customer service! Thank you for reaching out!

Milk gets stuck in the lid
Purchased for an international trip, I filled the inside canister with ice and poured my milk into the outside canister. If the bottle was tipped over at all, the milk would get stuck inside the lip and would explode everywhere when opening. Very disappointing and a lot of wasted milk. I then tried putting the milk into the inside canister and ice on the outside, which didn’t last very long because you can’t put too much ice in it and get the inside canister to fit.

Best Travel Buddy
I was looking for options to make traveling easier before our family vacation (4 months after birth) and trying to feel less anxious about the process. I was surprised how easy the Ceres Chiller is to use and it has been going out on the daily far easier as well. It holds almost a days worth of pumping sessions and keeps it cold all day long. I now want to gift one to all of my mom friends!

LOVE THEM
I love the Ceres Chill. It keeps milk cold for a long time, is very portable, and you can pump directly into it for easy storage. It’s great for on-the-go or when returning to work.

OG+ Chiller/Warmer
I just got my chiller/warmer and have used it a few times as a chiller. It keeps milk cold for my long shifts. I tested the outer chamber with ice and the ice still had not melted completely at the 36 hour mark. Overall, I am impressed with the product and I am excited to keep using it.

Ice melts too fast
The thermos stays cold but I find myself refilling the ice constantly as the ice melts too easily. I thought the ice would at least stay solid for at least 12 hours.

Streamlined pumping experience!
My Ceres Chill has been great for collecting milk pumped at work. I’m glad I got this set with 2 inner chambers, as I can freeze them alternatively, ensuring they’re frozen solid when I use them.

Makes pumping so much easier!
I went back and forth about purchasing because I wasn't sure how I felt about mixing milk, or whether I really needed this. After days of forgetting enough cups/lids/bags, I went ahead and ordered. This bottle has made my life so much easier! I have to pump on the go at all kinds of random places, and not having to fuss with a cooler and ice packs is so helpful. Plus (even though I shouldn't have to) I appreciate that it makes carrying milk around more discreet. Highly recommend this for anyone who is pumping regularly.
